Great job, and the examples will be really useful. I left only one question regarding the addition of python3-pytest dependency

It's a ROS dependency. There's a lint tool that verifies the deps of rosdep are the same as this file:

Without it this test fails: https://github.com/RobotLocomotion/drake-ros/actions/runs/25818202470/job/75853716222#step:7:2502.

Taking a look at this file is no longer used in the core bazel infra, so eventually we can remove it, I'll create a follow up to remove that.
